Precautions for Use

Do not exceed the opening range: Maximum opening 65mm. Do not forcibly clamp workpieces exceeding this size to avoid damaging the adjustment mechanism.

Avoid Impact Loads: Pliers are for static clamping. Do not strike the pliers body with a hammer or use them to pry heavy objects.

Regularly Check Adjusting Screws: Before use, ensure that the adjusting screws are tightened to prevent loosening during clamping and causing the workpiece to fall off.

Rust prevention and maintenance: Wipe clean after use, especially the teeth of the pliers. You can apply rust-preventive oil. Store in a dry environment.

Non-insulated tools: Do not use on live equipment.
